Red Lion RPGC0031 Single Channel Output Rotary Pulse Generator

Red Lion RPGC0031 is a single-channel rotary pulse generator that delivers 31 pulses per revolution, providing a precise, countable pulse stream tied to shaft rotation for speed and position sensing in industrial control systems. As part of the long-running RPGC family, this device represents an older generation that has been superseded by Red Lion's ZCG and ZFG series, which carry forward the same core functionality in newer designs and documentation. The 31 PPR specification defines its resolution, making it a straightforward option for basic rotation measurements when interfaced with counters or PLC inputs on legacy equipment. The RPGC0031 was discontinued by the manufacturer in 2011, and current availability is typically found only through refurbished or used channels.
